2 * Re-enable "fsck -l" when it is ready:
3 https://bugs.freedesktop.org/show_bug.cgi?id=79576#c5
5 * Should systemctl status \* work on all unit types, not just .service?
7 * enabling an instance unit creates a pointless link, and
8 the unit will be started with getty@getty.service:
9 $ systemctl enable getty@.service
10 ln -s '/usr/lib/systemd/system/getty@.service' '/etc/systemd/system/getty.target.wants/getty@.service'
12 * Dangling symlinks of .automount unit files in .wants/ directories, set up
13 automount points even when the original .automount file did not exist
14 anymore. Only the .mount unit was still around.
16 * properly handle .mount unit state tracking when two mount points are stacked one on top of another on the exact same mount point.
18 * shorten the message to sane length:
20 Cannot add dependency job for unit display-manager.service, ignoring: Unit display-manager.service failed to load: No such file or directory. See system logs and 'systemctl status display-manager.service' for details.
22 * sd_bus_unref() is broken regarding self-references and "pseudo thread-safety".
23 See the comment in sd_bus_unref() for more..
26 * Fedora: when installing fedora with yum --installroot /var/run is a directory, not a symlink
27 https://bugzilla.redhat.com/show_bug.cgi?id=975864
29 * Fedora: add an rpmlint check that verifies that all unit files in the RPM are listed in %systemd_post macros.
31 * Fedora: post FPC ticket to move add %tmpfiles_create to the packaging guidelines
35 * generator that automatically discovers btrfs subvolumes, identifies their purpose based on some xattr on them.
37 * support setting empty environment variables with Environment= and EnvironmentFile=
39 * tmpfiles: figure out relation between Z and m?
41 * systemd-notify: fake ucred of msg to PID of parent, if that works, with fallback to our own if it doesn't.
43 * machined/machinectl: sort IP addresses we return by scope and protocol
44 * machined: write NSS module for looking up IP addresses for machines
46 * timer units: actually add extra delays to timer units with high AccuracySec values, don't start them already when we are awake...
49 - hookup with networkd: NTP servers from dhcp
51 * a way for container managers to turn off getty starting via $container_headless= or so...
53 * figure out a nice way how we can let the admin know what child/sibling unit causes cgroup membership for a specific unit
55 * add a kernel command line option to enable the debug shell
57 * journalctl: add the ability to look for the most recent process of a binary. journalctl /usr/bin/X11 --pid=-1 or so...
59 * set NOTIFY_SOCKET also for control processes
61 * drop parsing of chkconfig header lines from service.c
63 * mount_cgroup_controllers(): symlinks need to get the label applied
65 * For timer units: add some mechanisms so that timer units that trigger immediately on boot do not have the services they run added to the initial transaction and thus confuse Type=idle.
67 * Add RPM macros for registering/unregistering binfmt drop-ins
69 * Add timeout to early-boot, and shut down the system if it is hit. Solves the laptop-in-bag problem and is useful for embedded cases
71 * ImmutableSystem=yes/no or so to mount /usr, /boot read-only/invisible, and leave /var and /etc writable
73 * InaccessibleHome=yes/no or so to hide /home and /run/user from a service
75 * Run most system services with cgroupfs read-only and procfs with a more secure mode
77 * sd-event: generate a failure of a default event loop is executed out-of-thread
79 * add "M" as recursive version of "m" to tmpfiles, then use it for
80 chowning /run/log/journal (but not /var/log/journal), so that we
81 adjust the perms of journal files created before tmpfiles ran.
83 * expose "Locked" property on logind sesison objects
85 * add bus api to query unit file's X fields.
87 * consider adding RuntimeDirectoryUser= + RuntimeDirectoryGroup=
89 * sd-event: define more intervals where we will shift wakeup intervals around in, 1h, 6h, 24h, ...
92 - Support LUKS for root devices
93 - Define new partition type for encrypted swap? Support probed LUKS for encrypted swap?
94 - Make /home automount rather than mount?
96 * improve journalctl performance by loading journal files
97 lazily. Encode just enough information in the file name, so that we
98 do not have to open it to know that it is not interesting for us, for
99 the most common operations.
101 * support transient mount units
103 * add an "input" group to udev logic and add all input devices to it
105 * add generator that pulls in systemd-network from containers when
106 CAP_NET_ADMIN is set, more than the loopback device is defined, even
107 when it is otherwise off
109 * MessageQueueMessageSize= and RLimitFSIZE= (and suchlike) should use parse_iec_size().
111 * "busctl status" works only as root on dbus1, since we cannot read
114 * implement Distribute= in socket units to allow running multiple
115 service instances processing the listening socket, and open this up
118 * socket units: support creating sockets in different namespace,
119 opening it up for JoinsNamespaceOf=. This would require to fork off
120 a tiny process that joins the namespace and creates/binds the socket
121 and passes this back to PID1 via SCM_RIGHTS. This also could be used
122 to allow Chown/chgrp on sockets without requiring NSS in PID 1.
124 * New service property: maximum CPU and wallclock runtime for a service
126 * introduce bus call FreezeUnit(s, b), as well as "systemctl freeze
127 $UNIT" and "systemctl thaw $UNIT" as wrappers around this. The calls
128 should SIGSTOP all unit processes in a loop until all processes of
129 it are fully stopped. This can later be used for app management by
130 desktop UIs such as gnome-shell to freeze apps that are not visible
131 on screen, not unlike how job control works on the shell
134 - manager property enumeration was broken when systemd moved to /usr/lib/
137 - implement per-slice CPUFairScheduling=1 switch
138 - handle jointly mounted controllers correctly
139 - introduce high-level settings for RT budget, swappiness
140 - how to reset dynamically changed unit cgroup attributes sanely?
141 - when reloading configuration, apply new cgroup configuration
142 - when recursively showing the cgroup hierarchy, optionally also show
143 the hierarchies of child processes
146 - allow creating auxiliary units with the same call
147 - add field to transient units that indicate whether systemd or somebody else saves/restores its settings, for integration with libvirt
148 - ensure scope units may be started only a single time
150 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
152 * when we detect low battery and no AC on boot, show pretty splash and refuse boot
154 * machined, localed: when we try to kill an empty cgroup, generate an ESRCH error over the bus
156 * libsystemd-journal, libsystemd-login, libudev: add calls to easily attach these objects to sd-event event loops
158 * be more careful what we export on the bus as (usec_t) 0 and (usec_t) -1
160 * unify dispatch table in systemctl_main() and friends
162 * Automatically configure swap partition to use for hibernation by looking for largest swap partition on the root disk?
164 * socket-proxyd: Use sd-resolve to resolve the server address
166 * rfkill,backlight: we probably should run the load tools inside of the udev rules so that the state is properly initialized by the time other software sees it
168 * After coming back from hibernation reset hibernation swap partition using the /dev/snapshot ioctl APIs
170 * If we try to find a unit via a dangling symlink, generate a clean
171 error. Currently, we just ignore it and read the unit from the search
174 * refuse boot if /etc/os-release is missing or /etc/machine-id cannot be set up
176 * given that logind now lets PID 1 do all nasty work, we can
177 probably reduce the capability set it retains substantially.
178 (we need CAP_SYS_ADMIN for drmSetMaster(), so maybe not worth it)
180 * btrfs raid assembly: some .device jobs stay stuck in the queue
182 * make sure gdm does not use multi-user-x but the new default X configuration file, and then remove multi-user-x from systemd
184 * man: the documentation of Restart= currently is very misleading and suggests the tools from ExecStartPre= might get restarted.
186 * load .d/*.conf dropins for device units
188 * allow implementation of InaccessibleDirectories=/ plus
189 ReadOnlyDirectories=... for whitelisting files for a service.
192 - make AddMatch calls on dbus1 transports async
193 - when kdbus does not take our message without memfds, try again with memfds
194 - systemd-bus-proxyd needs to enforce good old XML policy
195 - port exit-on-idle logic to byebye ioctl
196 - allow updating attach flags during runtime
197 - pid1: peek into activating message when activating a service
198 - introduce sd_bus_emit_object_added()/sd_bus_emit_object_removed() that automatically includes the build-in interfaces in the list
199 - constructors for bus messages should probably not be OK with a NULL bus pointer
200 - .busname units should not use get_user_creds()/get_cgroup_creds() but instead do NSS only in temporarily forked off child
201 - see if we can drop more message validation on the sending side
202 - add API to clone sd_bus_message objects
203 - kdbus: matches against source or destination pids for an "strace -p"-like feel. Problem: The PID info needs to be available in userspace too...
204 - longer term: priority inheritance
207 - NameLost/NameAcquired obsolete
209 - "const" properties (posted)
211 - update systemd.special(7) to mention that dbus.socket is only about the compatibility socket now
212 - test bloom filter generation indexes
213 - port to sd-resolve for connecting to TCP dbus servers
216 - allow multiple signal handlers per signal?
218 * in the final killing spree, detect processes from the root directory, and
219 complain loudly if they have argv[0][0] == '@' set.
220 https://bugzilla.redhat.com/show_bug.cgi?id=961044
222 * investigate endianness issues of UUID vs. GUID
224 * dbus: when a unit failed to load (i.e. is in UNIT_ERROR state), we
225 should be able to safely try another attempt when the bus call LoadUnit() is invoked.
227 * add a pam module that passes the hdd passphrase into the PAM stack and then expires it, for usage by gdm auto-login.
229 * add a pam module that on password changes updates any LUKS slot where the password matches
231 * maybe add a generator that looks for "systemd.run=" on the kernel cmdline for container usercases...
233 * timedatctl, localectl: possibly make some commands work without the daemon, for chroot situations...
235 * timedatectl: print a nicer message when enabling ntp fails because ntpd/chrony are not installed
237 * cgtop: make cgtop useful in a container
240 - add 'set -e' to scripts in test/
241 - make stuff in test/ work with separate output dir
243 * systemctl delete x.snapshot leaves no trace in logs (at least at default level).
245 * make the coredump collector tool move itself into the user's cgroup
246 so that the coredump is properly written to the user's own journal
249 * seems that when we follow symlinks to units we prefer the symlink
250 destination path over /etc and /usr. We should not do that. Instead
251 /etc should always override /run+/usr and also any symlink
254 * when isolating, try to figure out a way how we implicitly can order
255 all units we stop before the isolating unit...
257 * teach ConditionKernelCommandLine= globs or regexes (in order to match foobar={no,0,off})
259 * after all byte-wise realloc() is slow, even on glibc, so i guess we
260 need manual exponential loops after all
262 * BootLoaderSpec: Clarify that the kernel has to be in $BOOT. Clarify
263 that the boot loader should be installed to the ESP. Define a way
264 how an installer can figure out whether a BLS compliant boot loader
267 * think about requeuing jobs when daemon-reload is issued? usecase:
268 the initrd issues a reload after fstab from the host is accessible
269 and we might want to requeue the mounts local-fs acquired through
272 * systemd-inhibit: make taking delay locks useful: support sending SIGINT or SIGTERM on PrepareForSleep()
274 * journal-or-kmsg is currently broken? See reverted commit 4a01181e460686d8b4a543b1dfa7f77c9e3c5ab8.
276 * remove any syslog support from log.c -- we probably cannot do this before split-off udev is gone for good
278 * shutdown logging: store to EFI var, and store to USB stick?
280 * write UI tool that pops up emergency messages from the journal as notification
282 * think about window-manager-run-as-user-service problem: exit 0 → activate shutdown.target; exit != 0 → restart service
284 * use "log level" rather than "log priority" everywhere
286 * timedate: have global on/off switches for auto-time (NTP), and auto-timezone that connman can subscribe to.
288 * merge unit_kill_common() and unit_kill_context()
290 * introduce ExecCondition= in services
293 - honor language efi variables for default language selection (if there are any?)
294 - honor timezone efi variables for default timezone selection (if there are any?)
295 - change bootctl to be backed by systemd-bootd to control temporary and persistent default boot goal plus efi variables
297 * maybe do not install getty@tty1.service symlink in /etc but in /usr?
299 * re-enable "make check" for gtk-doc (broken for unknown reason)
301 * fstab: add new mount option x-systemd-after=/foobar/waldo to allow manual dependencies to other mount points
302 https://bugzilla.redhat.com/show_bug.cgi?id=812826
304 * print a nicer explanation if people use variable/specifier expansion in ExecStart= for the first word
306 * mount: turn dependency information from /proc/self/mountinfo into dependency information between systemd units.
309 - logind: optionally, ignore idle-hint logic for autosuspend, block suspend as long as a session is around
310 - When we update the kernel all kind of hibernation should be prohibited until shutdown/reboot
311 - logind: wakelock/opportunistic suspend support
312 - Add pretty name for seats in logind
313 - logind: allow showing logout dialog from system?
314 - we should probably handle SIGTERM/SIGINT to not leave dot files around, just in case
315 - session scopes/user unit: add RequiresMountsFor for the home directory of the user
316 - add Suspend() bus calls which take timestamps to fix double suspend issues when somebody hits suspend and closes laptop quickly.
317 - if pam_systemd is invoked by su from a process that is outside of a
318 any session we should probably just become a NOP, since that's
319 usually not a real user session but just some system code that just
322 * exec: when deinitializating a tty device fix the perms and group, too, not only when initializing. Set access mode/gid to 0620/tty.
324 * service: watchdog logic: for testing purposes allow ping, but do not require pong
327 - import and delete pstore filesystem content at startup
328 - journald: also get thread ID from client, plus thread name
329 - journal: when waiting for journal additions in the client always sleep at least 1s or so, in order to minimize wakeups
330 - add API to close/reopen/get fd for journal client fd in libsystemd-journal.
331 - fallback to /dev/log based logging in libsystemd-journal, if we cannot log natively?
332 - declare the local journal protocol stable in the wiki interface chart
333 - journal: reuse XZ context
334 - sd-journal: speed up sd_journal_get_data() with transparent hash table in bg
335 - journald: when dropping msgs due to ratelimit make sure to write
336 "dropped %u messages" not only when we are about to print the next
337 message that works, but alraedy after a short tiemout
338 - check if we can make journalctl by default use --follow mode inside of less if called without args?
339 - maybe add API to send pairs of iovecs via sd_journal_send
340 - journal: when writing journal auto-rotate if time jumps backwards
341 - journal: add a setgid "systemd-journal" utility to invoke from libsystemd-journal, which passes fds via STDOUT and does PK access
342 - journactl: support negative filtering, i.e. FOOBAR!="waldo",
343 and !FOOBAR for events without FOOBAR.
344 - journal: send out marker messages every now and then, and immediately sync with fdatasync() afterwards, in order to have hourly guaranteed syncs.
345 - journal-send.c, log.c: when the log socket is clogged, and we drop, count this and write a message about this when it gets unclogged again.
346 - journal: find a way to allow dropping history early, based on priority, other rules
347 - journal: When used on NFS, check payload hashes
348 - journald: check whether it is OK if the client can still modify delivered journal entries
349 - journal live copy, based on libneon (client) and libmicrohttpd (server)
350 - journald: add kernel cmdline option to disable ratelimiting for debug purposes
351 - refuse taking lower-case variable names in sd_journal_send() and friends.
352 - journald: we currently rotate only after MaxUse+MaxFilesize has been reached.
353 - journal: deal nicely with byte-by-byte copied files, especially regards header
354 - journal: store euid in journal if it differs from uid
355 - journal: sanely deal with entries which are larger than the individual file size, but where the components would fit
356 - Replace utmp, wtmp, btmp, and lastlog completely with journal
357 - journalctl: instead --after-cursor= maybe have a --cursor=XYZ+1 syntax?
358 - tmpfiles: when applying ownership to /run/log/journal, also do this for the journal fails contained in it
359 - when a kernel driver logs in a tight loop, we should ratelimit that too.
360 - journald: optionally, log debug messages to /run but everything else to /var
361 - journald: when we drop syslog messages because the syslog socket is
362 full, make sure to write how many messages are lost as first thing
363 to syslog when it works again.
364 - journald: make sure ratelimit is actually really per-service with the new cgroup changes
365 - change systemd-journal-flush into a service that stays around during
366 boot, and causes the journal to be moved back to /run on shutdown,
367 so that we do not keep /var busy. This needs to happen synchronously,
368 hence doing this via signals is not going to work.
371 - document that deps in [Unit] sections ignore Alias= fields in
372 [Install] units of other units, unless those units are disabled
373 - man: clarify that time-sync.target is not only sysv compat but also useful otherwise. Same for similar targets
374 - document the exit codes when services fail before they are exec()ed
375 - document that service reload may be implemented as service reexec
376 - document in wiki how to map ical recurrence events to systemd timer unit calendar specifications
377 - add a man page containing packaging guidelines and recommending usage of things like Documentation=, PrivateTmp=, PrivateNetwork= and ReadOnlyDirectories=/etc /usr.
378 - document systemd-journal-flush.service properly
379 - documentation: recommend to connect the timer units of a service to the service via Also= in [Install]
380 - man: document the very specific env the shutdown drop-in tools live in
381 - man: extend runlevel(8) to mention that runlevels suck, and are dead. Maybe add runlevel(7) with a note about that too
382 - man: add more examples to man pages
383 - man: maybe sort directives in man pages, and take sections from --help and apply them to man too
386 - systemctl list-jobs - show dependencies
387 - add systemctl switch to dump transaction without executing it
388 - Add a verbose mode to "systemctl start" and friends that explains what is being done or not done
389 - "systemctl disable" on a static unit prints no message and does
390 nothing. "systemctl enable" does nothing, and gives a bad message
391 about it. Should fix both to print nice actionable messages.
392 - print nice message from systemctl --failed if there are no entries shown, and hook that into ExecStartPre of rescue.service/emergency.service
393 - add new command to systemctl: "systemctl system-reexec" which reexecs as many daemons as virtually possible
394 - systemctl enable: improve the success messages (i.e. more human readable, less shell-like)
395 - systemctl enable: fail if target to alias into does not exist? maybe show how many units are enabled afterwards?
396 - systemctl: "Journal has been rotated since unit was started." message is misleading
397 - support "systemctl stop foobar@.service" to stop all units matching a certain template
398 - Something is wrong with symlink handling of "autovt@.service" in "systemctl list-unit-files"
399 - better error message if you run systemctl without systemd running
400 - systemctl status output should should include list of triggering units and their status
403 - "systemctl mask" should find all names by which a unit is accessible
404 (i.e. by scanning for symlinks to it) and link them all to /dev/null
405 - "systemctl disable" of a unit instance removes all symlinks, but should
406 only remove the instance symlink (systemctl disable of a template
407 unit however should remove them all).
408 - systemctl list-unit-files should list generated files (and probably with a new state "generated" for them, or so)
409 - systemctl: maybe add "systemctl add-wants" or so...
411 * deal with sendmail/postfix exclusivity
414 - timer units should get the ability to trigger when:
415 o CLOCK_REALTIME makes jumps (TFD_TIMER_CANCEL_ON_SET)
417 - Support 2012-02~4 as syntax for specifying the fourth to last day of the month.
418 - calendarspec: support value ranges with ".." notation. Example: 2013-4..8-1
419 - when parsing calendar timestamps support the UTC timezone (even if we will not support arbitrary timezone specs, support UTC itself certainly makes sense), also support syntaxes such as +0200
420 - Modulate timer frequency based on battery state
422 * update the kernel's TZ (sys_tz) when DST changes
424 * sync down the system time to the RTC when:
425 - CLOCK_REALTIME makes jumps (the user explicitely requested a time set)
426 - DST/timezone changes && ntp is active && RTC-in-localtime (never do it without ntp)
427 This takes care of syncing ntpdate updates to the RTC, and DST updates for localtime
428 mode, it will never touch the RTC if the no reliable time source is active or the
429 user did not request anything like it.
431 * libunwind support for coredump pattern hook, and includes this in
432 the message for coredumps. After all, libunwind is now capable to
433 unwind coredumps since a few weeks ago. This probably requires that
434 we have nice support for multi-line messages on display in
435 logs-show.c. Alternatively: use libelfutil, which seems to be the
436 better supported alternative.
438 * add libsystemd-password or so to query passwords during boot using the password agent logic
440 * If we show an error about a unit (such as not showing up) and it has no Description string, then show a description string generated form the reverse of unit_name_mangle().
442 * fedup: add --unit to systemctl switch-root somehow
443 * fedup: do not delete initrd on switch-root
446 * timedated: refuse time changes when NTP is on
448 * clean up date formatting and parsing so that all absolute/relative timestamps we format can also be parsed
450 * on shutdown: move utmp, wall, audit logic all into PID 1 (or logind?), get rid of systemd-update-utmp-runlevel
452 * add "factory" instructions to setup an empty /etc + /var
453 - used to setup a new container from a shared /usr
454 - superset of tmpfiles model
455 - instructions shipped by packages and stored in /usr/lib/
456 - compose /etc/passwd and /etc/group, copy files
457 - able to create uid + gid used by packages, for file ownership
459 * make repeated alt-ctrl-del presses printing a dump, or even force a reboot without
460 waiting for the timeout
462 * hostnamed: before returning information from /etc/machine-info.conf check the modification data and reread. Similar for localed, ...
464 * currently x-systemd.timeout is lost in the initrd, since crypttab is copied into dracut, but fstab is not
467 - nspawn: --read-only is not applied recursively to submounts
468 - bind mount read-only the cgroup tree higher than nspawn
469 - nspawn: make it work for dwalsh and shared /usr containers -- tmpfs mounts as command line parameters
470 - refuses to boot containers without /etc/machine-id (OK?), and with empty /etc/machine-id (not OK).
471 - support taking a btrfs snapshot at startup and dropping it afterwards
474 - cryptsetup-generator: allow specification of passwords in crypttab itself
475 - move cryptsetup key caching into kernel keyctl?
476 https://bugs.freedesktop.org/show_bug.cgi?id=54982
477 - support rd.luks.allow-discards= kernel cmdline params in cryptsetup generator
479 * hw watchdog: optionally try to use the preset watchdog timeout instead of always overriding it
480 https://bugs.freedesktop.org/show_bug.cgi?id=54712
482 * after deserializing sockets in socket.c we should reapply sockopts and things
484 * make timer units go away after they elapsed
486 * http://lists.freedesktop.org/archives/systemd-devel/2012-September/006502.html
487 (network and remote-fs on shutdown)
489 * come up with a nice way to write queue/read_ahead_kb for a block device without interfering with readahead
491 * move PID 1 segfaults to /var/lib/systemd/coredump?
493 * create /sbin/init symlinks from the build system
495 * Query Paul Moore about relabelling socket fds while they are open
497 * allow writing multiple conditions in unit files on one line
499 * explore multiple service instances per listening socket idea
501 * MountFlags=shared acts as MountFlags=slave right now.
503 * ReadOnlyDirectories= is not applied recursively to submounts
505 * drop PID 1 reloading, only do reexecing (difficult: Reload()
506 currently is properly synchronous, Reexec() is weird, because we
507 cannot delay the response properly until we are back, so instead of
508 being properly synchronous we just keep open the fd and close it
509 when done. That means clients do not get a successful method reply,
510 but much rather a disconnect on success.
512 * properly handle loop back mounts via fstab, especially regards to fsck/passno
514 * allow services with no ExecStart= but with an ExecStop=
516 * dracut-shutdown needs to be ordered before unmounting /boot
518 * initialize the hostname from the fs label of /, if /etc/hostname does not exist?
520 * rename "userspace" to "core-os"
522 * load-fragment: when loading a unit file via a chain of symlinks
523 verify that it is not masked via any of the names traversed.
525 * introduce Type=pid-file
527 * change Requires=basic.target to RequisiteOverride=basic.target
529 * when breaking cycles drop sysv services first, then services from /run, then from /etc, then from /usr
531 * automount: implement expire:
532 - set superblock timeout AUTOFS_DEV_IOCTL_TIMEOUT_CMD
533 - periodically run AUTOFS_DEV_IOCTL_EXPIRE_CMD
534 - every timeout/4 (original autofs logic)
535 - blocking, needs a thread
537 - receive expire packet on pipe if kernel tells the timeout is over
539 - answer expire packet on pipe with AUTOFS_DEV_IOCTL_{READY,FAIL}_CMD
540 - AUTOFS_DEV_IOCTL_EXPIRE_CMD returns
542 * ExecOnFailure=/usr/bin/foo
545 - remove src/udev/udev-builtin-firmware.c (CONFIG_FW_LOADER_USER_HELPER=n)
548 - add trigger --subsystem-match=usb/usb_device device
549 - reimport udev db after MOVE events for devices without dev_t
551 * when a service has the same env var set twice we actually store it twice and return that in systemctl show -p... We should only show the last setting
553 * introduce mix of BindTo and Requisite
555 * add DeleteSocketsOnStop=yes|no option to socket units
557 * There's currently no way to cancel fsck (used to be possible via C-c or c on the console)
559 * add option to sockets to avoid activation. Instead just drop packets/connections, see http://cyberelk.net/tim/2012/02/15/portreserve-systemd-solution/
561 * default unix qlen is too small (10). bump sysctl? add sockopt?
563 * save coredump in Windows/Mozilla minidump format
565 * support crash reporting operation modes (https://live.gnome.org/GnomeOS/Design/Whiteboards/ProblemReporting)
567 * default to actual 32-bit PIDs, via /proc/sys/kernel/pid_max
569 * be able to specify a forced restart of service A where service B depends on, in case B
570 needs to be auto-respawned?
572 * when a bus name of a service disappears from the bus make sure to queue further activation requests
575 - check systemd-tmpfiles for selinux context hookup for mknod(), symlink() and similar
576 - apply "x" on "D" too (see patch from William Douglas)
578 * for services: do not set $HOME in services unless requested
580 * hide PAM options in fragment parser when compile time disabled
582 * when we automatically restart a service, ensure we restart its rdeps, too.
584 * allow Type=simple with PIDFile=
585 https://bugzilla.redhat.com/show_bug.cgi?id=723942
587 * move PAM code into its own binary
589 * implement Register= switch in .socket units to enable registration
590 in Avahi, RPC and other socket registration services.
592 * make sure systemd-ask-password-wall does not shutdown systemd-ask-password-console too early
594 * support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
596 * support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
598 * verify that the AF_UNIX sockets of a service in the fs still exist
599 when we start a service in order to avoid confusion when a user
600 assumes starting a service is enough to make it accessible
602 * support User= and Group= attributes for AF_UNIX sockets. (difficult, requires NSS from PID 1?)
604 * Make it possible to set the keymap independently from the font on
605 the kernel cmdline. Right now setting one resets also the other.
607 * and a dbus call to generate target from current state
610 - drop /.readahead on bigger upgrades with yum
611 - move readahead files into /var (look for them with .path units?)
612 - readahead: use BTRFS_IOC_DEFRAG_RANGE instead of BTRFS_IOC_DEFRAG ioctl, with START_IO
613 - readahead: when bumping /sys readahead variable save mtime and compare later to detect changes
614 - readahead: make use of EXT4_IOC_MOVE_EXT, as used by http://e4rat.sourceforge.net/

633 - dynamic resource management with cgroups
634 - refreshed, longer missions statement
635 - calendar time events
636 - init=/bin/sh vs. "emergency" mode, vs. "rescue" mode, vs. "multi-user" mode, vs. "graphical" mode, and the debug shell
637 - how to create your own target
638 - instantiated apache, dovecot and so on
639 - hooking a script into various stages of shutdown/rearly booot
641 * allow port=0 in .socket units
643 * support systemd.mask= on the kernel command line.
645 * recreate systemd's D-Bus private socket file on SIGUSR2
647 * Support --test based on current system state

655 * fingerprint.target, wireless.target, gps.target, netdevice.target
657 * drop cap bounding set in readahead and other services
660 - figure out a simple way to wait for journal events in a way that
662 - add documentation to systemd.daemon
665 - plot per-process IO utilization
666 - group processes based on service association (cgroups)
667 - document initcall_debug
668 - kernel cmdline "bootchart" option for simplicity?
671 - Make sure ID_PATH is always exported and complete for
672 network devices where possible, so we can safely rely
674 - check MTUBytes parsing (expecting size_t but we are using unsigned)
677 - add support for more attribute types
678 - inbuilt piping support (essentially degenerate async)? see loopback-setup.c and other places
681 - add more keys to [Route] and [Address] sections
682 - add support for more DHCPv4 options (and, longer term, other kinds of dynamic config)
683 - send hostname to DHCP server
684 - add proper initrd support (in particular generate .network/.link files based on /proc/cmdline)
685 - add reduced [Link] support to .network files
686 - add Scope= parsing option for [Network]
687 - properly handle routerless dhcp leases
688 - set lifetime on the address acquired from dhcp

713 * patch kernel for xattr support in /dev, /proc/, /sys?
715 * kernel: add device_type = "fb", "fbcon" to class "graphics"
717 * drop accountsservice's StandardOutput=syslog and Type=dbus fields
719 * dbus upstream still refers to dbus.target and should not
721 * dbus: in fedora, make /var/lib/dbus/machine-id a symlink to /etc/machine-id
723 * add "# export SYSTEMD_PAGER=" to bash login
725 * /usr/bin/service should actually show the new command line
727 * fedora: suggest auto-restart on failure, but not on success and not on coredump. also, ask people to think about changing the start limit logic. Also point people to RestartPreventExitStatus=, SuccessExitStatus=
729 * fedora: F20: go timer units all the way, leave cron.daily for cron
731 * neither pkexec nor sudo initialize environ[] from the PAM environment?

753 Scheduled for removal or fixing:
755 * xxxOverridable dependencies (probably: fix)
